Let me do my part as a good user:

Can this be merged? Why hasn’t this been merged yet? Is the project dead? Is there a fork? Why are the devs not responding?

Thanks for the fix. :)

Dear @1cg ,

I would greatly appreciate it if you could review the current PR. Additionally, there are several other PRs specifically addressing issues related to Safari.

Thank you in advance for your time.

Hey, following up late on this ; since extensions have moved to another repo for v2, you'll want to either (ideally both if you feel like it!) retarget this PR to the v1 branch, or make another PR on that extensions repo!
